I believe there is a recall option on those machines. So far no one has identified what exactly is the problem there. I was reading the aac-raid list for a while, some people point the finger at the firmware on the disks, and some at the drivers. Either way, there are a few machines that Dell acknoledges trouble with. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
